The document introduces Commons RDF, an open source Java library that aims to provide common interfaces for working with RDF across different RDF frameworks. It was created due to historical incompatibilities between RDF Java libraries and provides type-safe APIs focused initially on core RDF 1.1 concepts like IRIs, blank nodes, literals, and triples. The library is currently hosted on GitHub but may eventually move to Apache Commons. It seeks feedback from the community on additional desired interfaces as the design evolves.

3. Commons RDF, why?
● Historical incompatibility in Java
● Not providing yet-another-wrapper
● But providing commons interfaces
● It arrives in the right time:
○ Apache Jena 3.0
○ OpenRDF Sesame 4.0
● But it will live or die on its own merits!

4. Features
● A type-safe, non-general API that covers RDF 1.1.
● Initial focused on a subset of the core RDF 1.1 concepts
○ IRI, Blank Node, Literal, Triple, and Graph
● In a future other aspects may be also included
○ datasets, query, etc.
Which other interfaces are desired by developers?

5. Design using Git workflows

6. Next steps and discussion
● Bootstrap the implementations on each toolkit
● Evolve the current design
● Get feedback from the commuity
● Currently working at Github, although at some point we
could move to Apache Commons or any suitable
organization
